Toenail tattoos

A guy named Peter Joye in Oregon started using his tattoo machine to etch tattoos in fingernails and toenails. His technique works the same as skin tattoos, using the same needle to send ink into the tissue. The process does not hurt as much as a skin tattoo, but people describe it as 'irritating'. Similar to turning on your car in the morning and that 'Crazy' song by Gnarls Barkley comes on.
There is a ridiculous 'Texas' fingernail tattoo here. The good thing is that they grow out as your nail grows.
